Old felt. Tired boards. Water standing for days after rain. Those are the roofs we replace in Rhymney. Each job begins with a survey and a written price, then a full strip and rebuild in the system that suits your roof, finished with fresh edges and outlets so water leaves the roof quickly.

When should a flat roof in Rhymney be replaced?

A flat roof in Rhymney is often worth replacing because it is the weak point of the building: heat escapes through an uninsulated deck, rooms below are cold in winter and hot in summer, and condensation marks the ceiling. A warm-roof replacement deals with comfort as well as leaks, so it is worth considering before the roof fails outright.

In and around Rhymney, flat roofs are typically found on terraced streets with flat-roofed rear kitchens and bathrooms, and on low-rise post-war blocks of flats. Wales averages roughly 1,460 mm of rain a year, among the wettest in Britain, so we design for steady run-off: proper falls, clear outlets and upstands well above the finished roof.

How much does a flat roof replacement cost in Rhymney?

For Rhymney we use Wales rates: £2,600–£4,500 is the guide for a 20 m² extension roof in EPDM with a new deck and insulation, VAT included. The fixed price comes after a free survey for new and replacement roofs.

How long does it take to replace a flat roof?

A garage or single-storey extension roof is usually stripped and re-covered in one to three working days; larger, higher or more detailed roofs take longer. Weather sets the pace, because the deck must be dry before insulation and membrane go down.

We strip only as much as can be made weathertight that day, so the roof is never left open overnight. Expect noise and some vibration during the strip, a skip on the drive (or on the road with a permit) and ladders or a tower against the house. Rooms below stay usable, though it helps to clear shelves near the ceiling. Resin systems such as GRP smell strongly while they cure, so keep nearby windows closed that day. Two-storey roofs need scaffold, which goes up before we start and comes down after sign-off.

What's included?

  • New membrane, upstands, edge trims and outlets
  • New deck, firrings and warm-roof insulation where needed
  • Strip-out of the old covering, with waste and skip
  • Fixed written quote listing the full build-up

Building regulations in Wales

The Welsh Approved Document L applies. Renovating more than half of a roof over a heated room means upgrading it to around 0.16 W/m²K where feasible, and new extension roofs are built to 0.13 W/m²K. Welsh Government guidance is that most re-roofing needs building control approval, so check whenever more than a quarter of a roof is replaced or repaired. We deal with the application as part of the job. More on the rules.

Who checks building regulations for a flat roof in Rhymney?

How much does a flat roof replacement cost in Rhymney?

£2,600–£4,500 for a 20 m² extension roof in EPDM with a new deck and insulation, at Wales guide rates including VAT. The fixed price comes after a free survey for new and replacement roofs.

What time of year is best for a flat roof replacement?

Late spring to early autumn gives the most reliable dry spells, but a roof can be replaced in any season when the forecast allows. Adhesives and resins have minimum application temperatures, so winter work is planned around mild, dry days.

Do I need to be at home while the roof is replaced?

Not for most of the job, as long as the team can reach the roof and there is room for a skip. We ask you to be there at the start to agree the plan and at the end to look over the finished roof.
